US Patent:

7213389, May 8, 2007
Filed:

Mar 2, 2004
Appl. No.:

10/791328
Inventors:

Joseph Albert Teijido - East Moline IL, US
Jeffrey Lee Wigand - Moline IL, US
Daniel Ray Anderson - Bettendorf IA, US
Robert Wayne Hawkins - Rapid City IL, US
Werner Stettler, Jr. - Cedar Falls IA, US
Helmut Weis - Massweiler, DE
Bernd Kempf - Althornbach, DE
Johann Hwang Pierce - Dewitt IA, US
Assignee:

Deere & Company - Moline IL
International Classification:

A01D 69/00
US Classification:

56 108
Abstract:

A mechanism for powering a combine header unit at infinitely variable speeds. A primary motor is coupled to a primary input shaft via a clutch, a variable-speed secondary motor is directly coupled to a secondary input shaft, and the header unit coupled to a header output shaft. A planetary gear-train couples the primary input shaft, the secondary input shaft, and the header output shaft to each other. A primary brake is coupled to the primary input shaft, and a secondary brake coupled to the secondary input shaft. A control circuit is employed to command the operation of the clutch, the secondary motor, the primary brake, and the secondary brake in response to operator commands.

US Patent:

7748489, Jul 6, 2010
Filed:

Oct 31, 2008
Appl. No.:

12/262901
Inventors:

Alan Sheidler - Moline IL, US
Johann Pierce - DeWitt IA, US
Assignee:

Deere & Company - Moline IL
International Classification:

B60K 7/00
B60K 17/14
US Classification:

180308, 180307, 180242, 701 50
Abstract:

An agricultural combine for supporting an agricultural header and carrying that agricultural header to a field to harvest a crop. The combine includes a chassis, front and rear drive wheels, a hydraulic motor, a device for sensing and a controller. The front and rear drive wheels support the chassis. The hydraulic motor is drivingly coupled to the front wheels. The device for sensing senses a presence of a header mounted to the combine. The controller is configured to monitor the device for sensing and to change the specific displacement of the hydraulic motor dependent upon the presence of the agricultural header.

US Patent:

8038518, Oct 18, 2011
Filed:

Apr 24, 2008
Appl. No.:

12/108576
Inventors:

Paul D. Marvin - Dewitt IA, US
Jeffrey A. Turigliatti - Geneseo IL, US
James K. Adamson - Colona IL, US
Todd E. Van Hal - Eldridge IA, US
Johann H. Pierce - Dewitt IA, US
Peter E. Kenyon - Davenport IA, US
Assignee:

Deere & Company - Moline IL
International Classification:

A01F 12/60
US Classification:

460119, 56 128, 460100
Abstract:

An agricultural combine includes a supporting structure. A work assembly is coupled to the supporting structure. The work assembly has a plurality of components to assist in the performing of crop processing operations. The work assembly is configured to define an air stream path. The work assembly has at least one rotary component that generates an air stream that flows through the air stream path to aid in crop processing in the work assembly. A fluid system is configured to circulate a fluid. The fluid system includes a fluid cooler that is positioned at a location in the air stream path to provide cooling of the fluid.

US Patent:

20030159416, Aug 28, 2003
Filed:

Feb 28, 2002
Appl. No.:

10/086055
Inventors:

Johann Pierce - East Moline IL, US
Joseph Teijido - East Moline IL, US
Dennis Roe - East Moline IL, US
International Classification:

A01D069/06
US Classification:

056/01020J, 056/011200, 460/016000
Abstract:

A mechanism is provided for engaging and disengaging the reverse operation of a feederhouse of a harvesting apparatus. The mechanism solves the problem of accurate engagement between the shift collar or driving element and the reverse gear, teeth or splines and the forward gear, teeth or splines of the feederhouse transmission. The mechanism comprises an actuator, electrically controlled, which loads or compresses a spring, wherein the spring exerts a shifting force on a shift shaft or shift fork of the gearbox which automatically moves the shift collar or driving element of the transmission into either a forward or reverse drive position when the gear, teeth of splines of the shift collar is aligned or meshed with the gear, teeth or splines of either the reverse or forward drive of the feederhouse transmission.
